Preliminary results of modifed cryogenic scleroplasty


Purpose: to assess preliminary results of modifed cryogenic scleroplasty efcacy in patients with progressing myopia. Material and Methods. Modifed cryogenic scleroplasty was developed by us in order to decrease the risk of deformation, torsion and displacement of scleroplastic material during its implantation. 38 children (72 eyes) aged 7–17 years with diagnosis of acquired progressing medium and high myopia with documented annual gradient of progressing more than 1 D were operated. 35 children (64 eyes) were the control group. They underwent standard scleroplasty by Pivovarov — Pristavko method. Results. No complications and adverse reactions to the transplantation material were observed during modifed cryogenic scleroplasty. Due to exposition in liquid nitrogen solution transplant keeps form and is not deformed during immersion and its partial location under the muscle. Stabilizing efect of the studied method (according to clinical refraction and axial length) is comparable to other types of scleroplasty. Conclusion. The developed technology of surgical treatment of progressing myopia is characterized by technological simplicity, convenience in material implantation, exclusion of transplant deformation and torsion on episclera surface, high stabilizing efect during the frst year after the surgery.
